I just submitted via Netfile and owe the CRA some Income Tax. Do I pay now - or wait for the NOA?

No upside paying before April 30. That is the filing and payment deadline.

I'm just thinking that I could pay now, but if they edit my return, then I might have to pay again, so I think I'll just wait until April 30th or I get the NOA - whichever comes first.

As others have mentioned, there is no benefit to paying earlier than April 30.

In your case, I would wait for April 30 to make the payment (regardless of whether the Notice of Assessment arrives earlier)

However, it depends on the amount. If the amount that I owe is what I consider to be "insignificant", I would pay it before April 30. Everyone has their own value but if it is under $100, I would probably pay it before April 30 since at most we are talking about possibly getting $0.15 interest (at 2% annual interest for 30 days for $100). I feel the same about credit cards. Some people (such as my parents) wait until the last possible day to pay their credit card bills even when the statement balance is only $15. They then risk not paying on the due date and paying an interest rate of ~22% from the date that the charge occurred (and not by how many days their payment is late). I can understand waiting for the last possible day to pay amounts due when the amount is high but don't see any point beyond "it is better in my hands than in their hands" until the due date.

I got my NOA email the next day, with no adjustments. Had to login to CRA to view it.
Will pay it now to get it out of the way.

As long as the value is "insignificant" like I mentioned earlier, I would do likewise.

For a larger amount, If it was $1k for example, for me, I would immediately schedule the one time payment online with my bank for April 27.

I scheduled the CRA to withdraw the payment from my chequing account on the due date.

I just hate giving the government money before it's due

And just for reference, April 30 is a Saturday. That means this year the payment due date is May 2.
